Title: Improvements in or relating to devices for laterally displacing material lying on the ground
IPC: A01D78/00
Filed: 1957-09-19
Abstract: 871,824. Haymaking machines. VAN DER LELY N.V., C. Sept. 19, 1957 [Sept. 29, 1956], No. 29560/57. Class 6(3). A rake-wheel type side-delivery rake having rake-wheels which either operate all in unison or in groups, for swath-turning, comprises a first frame 5, 12 supported on three ground wheels 16, 27, 28, and carrying a first group of rake-wheels 1, 2, and a second frame 47 carrying a second group of rake-wheels 3, 4, the second frame being attachable to the first at various positions corresponding to the different haymaking operations. The first frame comprises a cranked beam 5 passing through the bearings 8, 9 rotatable about the cranked beam but normally fixed by latches 10, 11 the rake-wheels 1, 2 being obliquely and freely rotatably arranged on the bearings. The beam terminates forwardly in a member 12, to which a front swivel-wheel 16 and drawbar 18 are attached and rearwardly in a member 26 carrying lockable swivel-wheels 27, 28 at its ends, all the swivel-wheels being height-adjustable. Both members 12, 26 carry a plate 23, 41 to which the beam 47 carrying the rake-wheels 3, 4 can be alternatively attached by pins 45, 46 passing through aligned holes 25 in the plates 23, 41 and in a plate 44 carried by the beam 47. For side-delivery the rake-wheels are arranged as shown and the device is drawn in the direction V ; for swath-turning, the beam 47 is attached to the plate 23, so that the rake-wheel groups are parallel but the device is drawn in the direction V.1., whereas, for tedding, the device is drawn in the direction W, but the bearings 8, 9 are all rotated through 180 degrees so that the rake-wheels occupy the chaindotted positions. The rearmost rake-wheel 4 is detachable to reduce the weight on the beam 47 during transference. Specification 871,825 is referred to.

H., Roselea, Gigg's Hill Green, Thames Ditton, VAUGHAN, S., Kenilworth, Old Coulsdon, and NATIONAL FIRE PROTECTION CO., Ltd., Petersham Road, Richmond, all in Surrey. Oct. 26, 1933, No. 29682. [Class 47 (ii)] In an extinguishing arrangement of the kind in which a container of liquid under pressure, with a rupturable seal and a spring-controlled plunger, is associated with, and readily dissociable from, a bracket with a seating connected to a sprinkler piping, means is provided whereby the outlet nozzle is unrestricted whilst the container is mounted in the bracket, but is automatically restricted when the container is removed from the bracket for hand use. As shown, a mushroom valve 3 with a hollow stem 5 is slidable in a bearing in the nozzle 1 and is biassed to its seat 3<a> by a spring 4. When the container a is mounted in its bracket e, the stem 5 engages a pin 7, whereby the valve 3 is displaced from its seat 3<a>. If now the seal b is ruptured by the piercer c, the liquid is discharged through the unrestricted nozzle 1 and ports 1<a> in the bearing into the piping f. If the container is detached for hand use, the valve 3 closes on its seat 3<a>, and liquid will now be discharged through the bore 6 in the stem 5. In a modification, the valve 3 is a piston valve co-operating with a coned seating in the nozzle. The piercer c may be actuated directly or indirectly by hand, or electrically.

Title: Improvements in or relating to the Pelletisation of Sulphur
Inventor: ELLIOTT HERBERT JAMES
IPC: C01B17/02
Filed: 1965-07-13
Abstract: 1,161,592. Pelletizing sulphur. ELLIOTT ASSOCIATED DEVELOPMENTS Ltd. 13 Oct., 1966 [13 July, 1965], No. 29696/65. Heading C1A. Pelletized sulphur is produced by introducing molten sulphur in super cooled condition into the top of a column containing water. The water should preferably be arranged to have a temperature gradient from the top to the bottom of the column. In one embodiment molten sulphur at a temperature between 96-119‹ C. is introduced into reservoir 11 at the top of column 12 and allowed to flow through the nozzles 13. The temperature of the water at the point of entry may be just above 100‹ C., slight pressure being applied to prevent boiling. The globules, formed from the stream in any appropriate way, pass down the column through the temperature drop at outlet 14 which is caused by introducing water at about 60‹ C. at the bottom of the column and withdrawing it at outlet 14. The globules are almost instantaneously solidified and are collected at 16 and let out through lock chamber 17. Alternatively, the sulphur may fall through an air space before entering the water and the use of an impeller in the water and addition of a silicone fluid to the water may also be incorporated.
